Plot a Trajectory Graph — plot_trajectory

Plots trajectory edges and optionally overlays selected node degrees. This plot is meant to be used as an additional layer in an UMAP plot.

Usage

plot_trajectory_graph(
  trajectory_object,
  edge_size = 0.5,
  edge_alpha = 1,
  edge_colour = "black",
  plot_nodes = c(1, 2, 3),
  node_size = 3,
  node_colours = stats::setNames(c("red", "blue", "green"), c(1, 2, 3)),
  node_label_size = 3,
  node_label_vjust = -1
)

Arguments

trajectory_object: A trajectory object produced by get_trajectory_object.
edge_size: Line width for trajectory edges.
edge_alpha: Transparency of trajectory edges.
edge_colour: Colour of trajectory edges.
plot_nodes: Which node-degree groups to display: 1 for leaves, 2 for intermediate nodes, 3 for branching points. Setting to 0 will hide all nodes.
node_size: Point size for trajectory nodes.
node_colours: Named colours for node-degree groups.
node_label_size: Text size of node labels.
node_label_vjust: Vertical adjustment for node labels.

Value

A ggplot object of the trajectory.
